Nursing Elites

1. A nurse is preparing to administer ampicillin 500 mg IV bolus every 6 hours. Available is ampicillin 500 mg in 50 mL dextrose 5% in water (D5W) to infuse over 20 minutes. The nurse should set the IV pump to deliver how many mL/hr?

• A. 100 mL/hr
• B. 150 mL/hr
• C. 200 mL/hr
• D. 250 mL/hr

Correct answer: B

Rationale: To infuse 50 mL over 20 minutes, the pump should be set to 150 mL/hr. This calculation ensures the correct rate for the infusion of the medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the given information.

2. A healthcare provider is providing dietary teaching for a client who has a burn injury and adheres to a vegan diet. The healthcare provider should recommend which of the following foods as the best source of protein to promote wound healing?

• A. One cup of brown rice
• B. One cup of pureed avocado
• C. One cup of lentils
• D. One cup of orange juice

Correct answer: C

Rationale: Lentils are an excellent source of protein, suitable for a vegan diet, and promote wound healing. Brown rice (Choice A) is a carbohydrate-rich food and lacks sufficient protein for wound healing. Pureed avocado (Choice B) is a healthy fat source but low in protein. Orange juice (Choice D) is a source of vitamin C but lacks protein needed for wound healing.

3. A patient on mechanical ventilation experiences a sudden drop in oxygen saturation. What should the nurse check first?

• A. Check the ventilator tubing for disconnection.
• B. Increase the patient's oxygen flow.
• C. Perform a full physical assessment.
• D. Reassess the patient's oxygen levels after 5 minutes.

Correct answer: A

Rationale: The correct answer is to check the ventilator tubing for disconnection first when a patient on mechanical ventilation experiences a sudden drop in oxygen saturation. This is crucial because equipment malfunction, such as tubing disconnection, can lead to decreased oxygen delivery, resulting in a drop in oxygen saturation. Checking the tubing ensures that the ventilation system is functioning properly and that the patient is receiving the necessary oxygen. Option B is incorrect because increasing oxygen flow without checking for equipment issues may not address the root cause of the drop in saturation. Option C is not the priority in this situation as the immediate focus should be on assessing and ensuring the functioning of the ventilation equipment. Option D delays addressing the potential equipment malfunction, which could worsen the patient's condition if not promptly resolved.

4. A client is prescribed 1g of potassium phosphate IV to be infused continuously over 6 hr. Available is 1 g in 250 ml of dextrose 5%. What rate should the nurse set the IV pump to run at?

• A. 40 ml/hr
• B. 42 ml/hr
• C. 44 ml/hr
• D. 46 ml/hr

Correct answer: B

Rationale: To calculate the IV rate, divide the total volume by the total time in hours. In this case, 1 g in 250 ml is to be infused over 6 hours. Therefore, 250 ml / 6 hr = 42 ml/hr. This means the IV pump should be set to run at 42 ml/hr. Choices A, C, and D are incorrect as they do not accurately calculate the infusion rate based on the provided information.

5. A nurse is providing home care for a client who is receiving tube feedings and medication through a gastrostomy tube. The family member providing the feedings reports that the client has begun to have diarrhea. For which of the following practices should the nurse intervene?

• A. Cleanse the bag every 24 hours
• B. Cleanse the bag every 48 hours
• C. Use tap water
• D. Flush the tube every 4 hours

Correct answer: A

Rationale: The correct answer is A. Cleansing the bag every 24 hours can lead to contamination, increasing the risk of infection and diarrhea. Using tap water (choice C) is not recommended for cleaning the gastrostomy tube due to the risk of introducing harmful microorganisms. Cleansing the bag every 48 hours (choice B) is not frequent enough and may also contribute to infection. Flushing the tube every 4 hours (choice D) is a standard practice to ensure patency and should not be intervened by the nurse.
